PHP - Php Script Keeps Loading...

Hi!

This code, which is basically HTML and Javascript, echoed in PHP (as you can see in the attached image), has functioned well for a long time. It still does, if put in a page by itself. The problem now is when it is integrated in other PHP scripts. It does not work this way on either the live server or on WAMP anymore. This script is normally setup to be execute about half way through the complete script of the page and has functioned well, showing approx. the top half of the page, as well as a loading gif. When the PHP workload is complete, the loading gif is removed and the rest of the page is displayed.

Now with the later versions of PHP, all I see is a blank page until all the script is executed, which can take about 15 seconds or more. PHP does not release the information to Apache, or if it does, Apache does not do anything with it. I have tried different approaches, using ob_flush() and so on, but it just will not function. I would like to know if someone else has had this issue, or knows about it and if there is any current solution. I have not managed to find any working solution that will work with PHP 7.4 and in the future, on the net.

I know one cannot predict all the changes that will occur with PHP in the future, but I would like the solution to function for at least 3-5 future versions. I am now going to try something completely different outside the box and create a start page instead. If it does work, it will just be a temporary solution though.

Thanks for any assistance beforehand.

Hello everyone,

I have a PHP shopping cart I am working on. I have all my pictures stored in a folder url directory of my project. In my SQL database I have an image table that holds all of the image names. When I load the picture names with my php It somehow adds some extra random characters to the directory path:

/img/%7B$row_product_image[name]%7D 404 (Not Found)

If I hardcode the image directory img/picturename.jpg It works.

Here is what I have.

<?php
    include_once "objects/database.php";
    include_once "objects/product.php";
    include_once "objects/product_images.php";
// object instances
$database = new Database();
$db = $database->getConnection();
$product = new Product($db);
$product_image = new ProductImage($db);
$recordsPerPage = 1;
while($row = $stmt->fetch(PDO::FETCH_ASSOC)) {
        extract($row);
        echo '<div class="col-md-4 mb-2">';
            echo '<div class="product-id d-none">{$id}</div>';
                echo '<a href="product.php?id={$id}" class="product-link">';
                    $product_image->product_id = $pid;
                    $stmt_product_image = $product_image->readFirst();
                    while($row_product_image = $stmt_product_image->fetch(PDO::FETCH_ASSOC)) {
                        echo '<div class="mb-1">';
                            echo '<img src="img/{$row_product_image[name]}" class="w-100" />';
                        echo '</div>';
                    }
                    echo '<div class="product-name mb-1">{$name}</div>';
                echo '</a>';

        echo '</div>';
    }
    class ProductImage {
        private $pdoConn;  private $table_name = "product_images";
        public $id;
        public $product_id;
        public $name;
        public $timestamp;
        public function __construct($dbconn) {
            $this->pdoConn = $dbconn;
        }
        function readFirst() {
            // SELECT query
            $query = "SELECT id, pid, name " .
                     "FROM " . $this->table_name . " " .
                     "WHERE pid = ? " .
                     "ORDER BY name DESC " .
                     "LIMIT 0, 1";
            // prepare query statement
            $stmt = $this->pdoConn->prepare($query);
            // sanitize
            $this->product_id=htmlspecialchars(strip_tags($this->product_id));
            // bind variable as parameter
            $stmt->bindParam(1, $this->product_id);
            // execute query
            $stmt->execute();
            // return values
            return $stmt;
        }
    }
